Rubio spokesman Joe Pounder was even more forceful than the
Florida senator. In a statement, Pounder said:

Senator Cruz is up to his dirty tricks again spreading false
rumors and lies. We won't allow him to do to Marco Rubio in
Florida what he did to Ben Carson in Iowa. Floridians and voters
across the country will reject Senator Cruz's campaign of
disgusting tactics because they know a vote for Cruz is a vote
for Donald Trump.

A Rubio campaign source told Business Insider that his team was
also aware of "numerous" Cruz operatives in Hawaii who were
allegedly telling voters that Rubio was going to drop out soon.
Hawaii's Republican caucuses are on Tuesday.

But Cruz's campaign issued a statement that attributed the dustup
to "volunteers" who didn't have the authority to send such
messages on behalf of the campaign:

Rubio's camp then called out the Cruz campaign's response in an
email to supporters and said it was the same "excuse" Cruz's
operatives used for the Carson incident:

It’s happening again. Supporters of Ted Cruz are now doing to
Marco what his campaign did to Ben Carson: circulating false
rumors about the state of our campaign. In fact, now that they’ve
been caught, they’re even using the same excuse as last time!

Remember: this was the scandal that completely undermined the
credibility of Ted Cruz and his campaign. He even had to fire a
top aide after he was caught spreading disinformation about
Marco’s Christian faith. And this is just the tip of the iceberg.
